Speaking of databases, how is the Argus database updated?
The Argus 3000 database is contained on four EPROMs and must be updated by a shop or at Eventide. Subscriptions are not available. The databases used in the Argus 5000 and Argus 7000 are contained on printed circuit cards and can be easily replaced in minutes by you or your avionics dealer. They are available by subscription, or on a one-time basis. Of course, we strongly recommend that you order a subscription, for reasons of both safety and convenience. (If you are flying with an IFR-approved long range navigation system and the Argus is approved for IFR use, the FAA requires that the Argus database meet IFR requirements.) If you fly VFR in a limited area, you might want to update the Argus on an as-needed basis, such as when a local airport opens or closes, when a navaid is relocated or as airspace is reclassified.
